You can display related listings inside your single listing page, based on any custom criteria that you can easily specify.
How to manage the related listings?
Navigate to your admin dashboard, then go to Listing Types (edit specific listing type) Listing Similar`, mark the option `Enable Similar Listings`. Then you will be able to create a relation between the listings by using the option `Similar Listing Relation`.
Basically you make the relation by taxonomy, which means that when you edit a single listing with taxonomy `Air Condition`, it will offer you more listing with the same taxonomy, ordered by date of publishing.
